I am looking for any advice/trick to get a better adhesion between my paint and resin. I always wipe my baits down with denatured alcohol before I paint them and they are completely demolded. So I am not having any bubbling problems.
1) is there a certain kind of primer that is far better?
2) Does heating the bait up in the oven right before painting make a big difference?
3) is there some other chemical I should be applying before painting?
4) any other tips is much appreciated

I have used HS1, HS2, and HS3 and the HS3 definitely last the longest but it still ends up breaking over time. It is also so soft. I don't feel like I get as consistent of baits using it because of the resin with microballons expanding.

I have used Oomoo and Alumilite but it doesn't seem they last very long before they start breaking. I have some baits with moderate undercuts and chucks of the mold start to break off. What can I do to decrease the number of molds I have to make? Is there a product product that works better? Is it possible to use aluminum mold with resin?

I have some multi joint swibaits that I think are coming along pretty well that I am making out of resin. Currently I pour the bait then I drill in the space for the weights and put in the screw eyes etc. I was wondering how to set up a mold so that I molded everything into the bait.... at the very least to mold the weights in?
Thank you

Thanks, that helps alot.
One more question. When you do large eyes like that they will still be mostly flattened. Anyone know how to makes eyes that big but basically have them be half a sphere. Looking to get a really buggy look. Almost like if I was to cut a marble in half kind of thickness.

I am looking for some info on making eyes. I want to make some big eyes for some of my swimbaits and make them in a bunch of different colors. Has anyone made custom eyes say anywhere from 6 mm to 12mm eyes? What material do I use?
